FORCE-PUMP.

SPECIFICATION forming part of Letters Patent No. 236,930, dated January 25, 1881. Application tiled April 6, 1880. (No model.)

To all whom @t may concern:

Be it known that I, PETER BREIDENBACH, a citizen of the United States, residing at Kenton, in the county of Hardin and State of Ohio, have invented certain new and useful Improvements in Force-Pumps; and l do hereby' declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereou, whichform a part of this specification.

My invention relates to improvements in force-pumps for which I have obtained Letters Patent ofthe United States under date of July 8, 1879, No. 217,328.

The objectof the invention is to perfect the pump by making it more efficient, easier of operation and simpler in construction; and to that end this invention consists in a certain novel arrangement and construction of pumpbrake combined with a platform and the piston-rod; and it further consists in a novel arrangement of the valves, as fully described hereinafter, and shown in the accompanying drawings, in which- Figure 1 is an isometrical view of vmy improved pump. Fig. 2 is a top-plan view of the lower valve-case. Fig. 3 is a likevview of the piston, and Figa a section on line m a: of Fig. 3. Fig. 5 is a vertical transverse. section of the pump and platform, and Fig. 6 a plan view of the piston-valve casing.

Like letters of reference are employed in the above figures of drawings to indicate like ,part-s wherever such may occur.

A is a, platform, preferably made of metal,

and having cast therewith or bolted thereto, 'a t opposite ends, the beariu g standard or brackets a a a. The platform is further provided with an aperture,- a2, in which the piston-rod or pipe coupled therewith reciprocates, and au aperture, a3, in which reciprocates the connecting-link of the pump-brake.

B is the pump-cylinder, open at its lower end, and provided with the lateral "vertical water-.passage b, arranged in theusual manner,

and havingat its lower and upper-'ends the inlet and outlet ports to admit water from the valve-casing into the cylinder above the piston.

Gis the induction-valve casin g, bolted to the lower end of the pump-cylinder. It is provided with valve-ports and disk-valves O C2, the former to draw water into and through the lateral chamber b into the cylinder B above the piston, and thc latter to draw water into the cylinder below the piston. These valves are constructed and arranged precisely as described in the above-mentioned Letters Patent, except that I employ only two valves instead of four.

D is the hollow piston-rod, carrying the cylindrical piston-head D', provided with three inlet-ports, d d d2, in its upper face around the hollow piston-rod D. The piston-head D carries within it a valve-plate, E, provided with three valve-ports and disk-valves, e e c, conaxial with, or practically con axial with, the inlet-ports d d' d2, to adapt the said valves to close said ports from within at each downstroke of the piston and eject the water admitted by valves O2 through the hollow pistonrod, returning to their seats at each upward stroke, at which time the water admitted through ports d d d2 from above the pistonhead is ejected through the hollow piston-rod, thus adapting the pump to eject water both ways-that is, at each upward or downward stroke, as will be readily understood.

The valves and their respective chambers in the piston-head are constructed substantially like those described in my Letters Patent above lnentioned, except that here I employ only three instead of four valves, and that the valve plate or casi n g E is so arranged and constructed as to enable me to dispense with the bridge-pieces employed to hold the valves in their chambers and prevent them from tilting or turning on edge and becoming inoperative. By an inspection of Figs. 5 and 6 it will be seen that the valve-casing E fits closely to the roof of the piston-head, and that the valvechambers are so arranged as to guide the valves properly to and from their seats in the valve-casing and the ports d d d2 in the piston-head D', the said Valve-chambers opening into a central space, e3, or passage, from which the water passes to the hollow piston-rod D.

IOO

By this arrangement the construction of the valve-casing E is greatly simplified, while the operation ofthe valves is not impeded.

The pump-cylinderis provided with bearing or bolt tlanges b', by means of which it is bolted to a bearing-plate, A', cast in one piece with the platform.

F F are two roller-bearings, bolted to the plate A and provided with bearing-slotsf, for the axes of two anti-t'riction rollers, G G, and a central opening or slot.f, of a dialneter slightly greater than that of the rolleraxes, through whichV the rollers may be readily inserted into the bearings and maintained in proper position, without further attachment, by the piston-rod D, which passes upward between the hearings and rollers and through the aperture a2 ofthe platform, having the usual pump-nozzle connected to its upper end. By means of this arrangement ofantifrietion roller-guides the piston-rod is always maintained in the lille of the axis of the pump-cylinder, which is very important to the good operation of the pump, as any deviation of the pistonrod from the said line will cause the pistonhead to bind within the pumpcylinder, and consequently require great power to work the pump and produce a corresponding wear of the parts.

To still further reduce the power required t0 operate this class of pumps. I employ the following novel arrangement and construction of devices:

I is a brake-lever, formed of the oblong open frame i, having at one end an arm. i', that is pivoted to the bearingdng, post, or bracket a depending from and cast with or attached to one end of the platform A. At the opposite end the open frame i has two ears or lugs, i? i2, between which is pivoted one end ot' the connectingrod K, that passes through the platform-aperture a, and is pivoled at its upper end to the outer end of the brake-arm L, pivoted near its rear end in the bracket-bearing a' of the platform. The brake or lever L has a weighted and socketed enlargement at its rear end for the reception of the brake-handle or hand-lever I, as shown, the parts, in practice, being so arranged and constructed that the weight end ot' the brake-arm L will counterhalance, or nearly so, the parts directly and indirectly connected therewith-that is to say, the connecting-rod K, the brake or oscillating lever I and its bearing-block M, and the piston -rod I). The latter passes through said bearing-block,aml is held against movement therein by the set-screw m, the block M oscillating upon pivots or trunnons or set-screws m m' in the open frame i of the brake-lever I.

Any one conversant with this class of ap paratus will be able to see at a glance the advantages obtained by this novel arrangement of brake-lever and anti-friction roller-guide.

Another advantage in this improved construction of pump liesin the fact that thepumpcylinder need not necessarily be immersed in the water that is to be elevated, as I am enabled to locate the cylinder at least thirty feet above the level of the water and work the pump with as great facility and eciency as it' said cylinder were immersed. I am thus enabled to locate the cylinder in almost all cases immediately underneath the platform, and secure it thereto and obtain ready access to said cylinder at all times without descending into the well and raising the cylinder and its parts, and the pipes connected therewith, to the surface.

I am aware that it is not new to employ anti-friction rollers as guides for a pump-rod, nor that of employing a weighted brake-lever to counterbalance the weight ofthe operating devices of a pump. I am further aware that the use cfa swivel or a pivoted bearing-block to operate the pump-rod or hollow piston-rod is also old, and I do not wish to claim them, broadly.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is-

1. 1n a pump of the class described, the platform A, having the bearing-brackets or lugs a a' aml a supporting-plate, A', for the roller-guides, and pump-cylinder and apertures a2 a3, all cast in one piece, in combination with said pump-cylinder and its operating devices, as and for` the purpose specified.

L. In a pump of the class described, the

combination, with the supporting-plate A of loo the platform A and the antifriction rollers G, ofthe brackets F, having the horizontal slots f for the roller-axes, and the vertical slots f 2 for the insertion or withdrawal of said rollers to or from their bearings, as set forth.

3. In a pump ot' the class described, the combination, with the platform A and plate A and the brackets I", having horizontal slots fand the vertical slots f', of the anti-friction rollers G, the hollow piston-rod, and appliances to reciprocate the latter, all arranged to operate substantially as and for the purpose specilied.

4. The combination, with the hollow' pistonrod D, of the brake composed of the open frame I, provided with an extension or arm, i', and bearing-lugs il, the adjustable pivoted block M, connecting-rod K, lever L, and handle l, and the platform A, having bearingbrackets a a', all arranged to operate as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
